12:10a	CPU Benchmarks: Pre-Release Intel Alder Lake Chip Beats Apple's M1 Max An anonymous reader quotes a report from ZDNet: The reign of Apple's M1 SoC at the top of the Geekbench speed benchmarks may soon be over with the impending arrival of Intel's 12th-generation Alder Lake mobile processors. Hardware site Wccftech appears to have been leaked Intel's upcoming Core i9-12900HK mobile CPU, and has now revealed the first benchmarks. The results show Intel's mobile CPU narrowly outperforming Apple's flagship 10-core M1 Max, which also integrates a 32-core GPU and 64GB of unified memory. In these latest tests, the Core i9-12900HK outperforms the M1 Max on both single-core and multi-core benchmarks. The margin is slim, but is important for Intel since Apple ditched its CPUs for its own designs in new MacBooks. Intel's Alder Lake CPU didn't beat the M1 Max by much, with respective single-core scores of 1851 and 1785. It beat the Core i9-11980HK and AMD's top mobile CPU, the Ryzen 5980HX, by a bigger margin: the latter two CPUs saw scores of 1616 and 1506, respectively. In the multi-core benchmark, the Core i9-12900HK scored 13256 versus the M1 Max's score of 12753. Again, it trounced AMD's 5980HX, which scored 8217. Wccftech's Alder Lake benchmarks were run using Windows 11, so it's possible Thread Director's hardware scheduling influenced the results. Read more of this story at Slashdot. (Comment on this)
1:30a	Argon Fluoride Laser Could Lead To Practical Fusion Reactors The US Naval Research Laboratory (AFL) is developing an Argon Fluoride (ArF) laser that may one day make fusion power a practical commercial technology. New Atlas reports: The wide-bandwidth ultraviolet laser is designed to have the shortest laser wavelength that can scale up to power a self-sustaining fusion reaction. [...] The NRL's ArF laser is intended for a test facility based on the principle of Inertial Confinement Fusion (ICF). In this, a bead of deuterium or tritium, which are heavy isotopes of hydrogen, is fired upon by multiple lasers, heating and compressing it in a fraction of a second to such an extent that the hydrogen atoms implode, fuse together, and release enormous amounts of energy. The new deep ultraviolet laser, also known as a laser driver, is claimed to transfer energy to the fuel bead with greater efficiency and produces much higher temperatures to generate the implosion. Using radiation hydrodynamics simulations the NRL scientists say that performance could be increased a hundredfold with an efficiency of 16 percent, compared to only 12 percent from the next most efficient krypton fluoride laser. Because of these improvements, the ArF laser could lead to smaller and less expensive fusion power plants. However, the team stresses that there is still a long way to go before fusion is hooked up to the national grid. The laser will need to provide the required energy, repetition rate, precision, and billion-shot class reliability for a practical plant. To move towards this, the laboratory is running a three-phase program with the first dedicated to the basic science and technology of the ArF laser. This will be followed by phase two, which will concentrate on building and testing a full-scale high-energy ArF laser, and then phase three where an implosion facility consisting of 20 to 30 lasers will be constructed. "The advantages could facilitate the development of modest size, less expensive fusion power plant modules operating at laser energies less than one megajoule," says Steve Obenschain, Ph.D., a research physicist at NRL. "That would drastically change the existing view on laser fusion energy being too expensive and power plants being too large." The research was published in the Philosophical Transactions of the Royal Society. Read more of this story at Slashdot. (Comment on this)
10:00a	China To Cut Fossil Fuel Use To Below 20% By 2060 China is targeting a clean energy goal of reducing fossil fuel use to below 20% by 2060, according to an official plan published by state media. The Guardian reports: The cabinet document, released on Sunday, follows a pledge by President Xi Jinping to wean the world's biggest polluter off coal, with a target of peaking carbon emissions by 2030 and achieving carbon neutrality 30 years later. But the country has been criticized for pushing ahead with opening dozens of new coal-fired power plants. Authorities have also been wanting to ramp up production, with coal prices surging and supplies running low, both factors behind recent power outages. The guidelines come as countries gear up for a new round of climate talks in Glasgow starting on 31 October, from which Xi will be conspicuously absent. China faces a struggle to wean itself off coal, which fuels nearly 60% of its energy-hungry economy. But on Sunday guidelines published by China's official Xinhua news agency laid out a host of targets in its path towards carbon neutrality. Among them was the proportion of non-fossil fuel consumption reaching about 25% of total energy use by 2030 -- when the nation targets peak emissions. By then, carbon dioxide emissions per unit of GDP would have dropped by more than 65% from 2005 levels, while the total installed capacity of wind and solar power is targeted to reach more than 1,200 gigawatts, Xinhua said. The guidelines also reiterated an earlier aim for carbon emissions per unit of GDP to fall 18% in 2025, from 2020 standards. Read more of this story at Slashdot. (Comment on this)
2:06p	AnandTech Reviews Apple's M1 Pro and M1 Max Chips AnandTech reviews the recently unveiled M1 Pro and M1 Max chips : The M1 Pro and M1 Max change the narrative completely -- these designs feel like truly SoCs that have been made with power users in mind, with Apple increasing the performance metrics in all vectors. We expected large performance jumps, but we didn't expect the some of the monstrous increases that the new chips are able to achieve. On the CPU side, doubling up on the performance cores is an evident way to increase performance -- the competition also does so with some of their designs. How Apple does it differently, is that it not only scaled the CPU cores, but everything surrounding them. It's not just 4 additional performance cores, it's a whole new performance cluster with its own L2. On the memory side, Apple has scaled its memory subsystem to never before seen dimensions, and this allows the M1 Pro & Max to achieve performance figures that simply weren't even considered possible in a laptop chip. The chips here aren't only able to outclass any competitor laptop design, but also competes against the best desktop systems out there, you'd have to bring out server-class hardware to get ahead of the M1 Max -- it's just generally absurd. On the GPU side of things, Apple's gains are also straightforward. The M1 Pro is essentially 2x the M1, and the M1 Max is 4x the M1 in terms of performance. Games are still in a very weird place for macOS and the ecosystem, maybe it's a chicken-and-egg situation, maybe gaming is still something of a niche that will take a long time to see make use of the performance the new chips are able to provide in terms of GPU. What's clearer, is that the new GPU does allow immense leaps in performance for content creation and productivity workloads which rely on GPU acceleration. To further improve content creation, the new media engine is a key feature of the chip. Particularly video editors working with ProRes or ProRes RAW, will see a many-fold improvement in their workflow as the new chips can handle the formats like a breeze -- this along is likely going to have many users of that professional background quickly adopt the new MacBook Pro's. For others, it seems that Apple knows the typical MacBook Pro power users, and has designed the silicon around the use-cases in which Macs do shine. The combination of raw performance, unique acceleration, as well as sheer power efficiency, is something that you just cannot find in any other platform right now, likely making the new MacBook Pro's not just the best laptops, but outright the very best devices for the task. It's a comprehensive review, and Intel should be panicking. Read more of this story at Slashdot. (Comment on this)
